Physics means getting physical if you’re tackling the biggest, most mysterious questions in the universe. Stoic scientists endure the driest, darkest, coldest spots on the planet to find out how it all began and why there’s something rather than nothing. From the bottom of an old iron mine to the top of the Andes, we’ll hear their stories. Plus, Steven Weinberg on this weird stuff called dark energy, and Leonard Susskind sees double, no, triple, no, …infinite universes. Guests: Anil Ananthaswamy - Corresponding editor for New Scientist magazine in London and author of The Edge of Physics: A Journey to Earth's Extremes to Unlock the Secrets of the Universe Steven Weinberg - Nobel Prize-winning physicist at University of Texas at Austin and author of Lake Views: This World and the Universe Leonard Susskind - Professor of theoretical physics, Stanford University André de Gouvêa - Associate professor of physics, Northwestern University Descripción en español Learn more about your ad choices.
